Si8452BA-IS1 5 Channel 1kV Digital Isolator

The Si8452BA-IS1 digital isolator is part of the industry’s highest-performance, easiest-to-use, and lowest-cost line of 2,500 to 5,000 kVrms rated digital isolators for I²C and SMBus serial port applications. . The  Si8452BA-IS1 isolator is based on Silicon Labs proprietary RF isolation technology and offer shorter propagation delays, lower power consumption, smaller installed size, and more stable operation with temperature and age versus opto couplers or other digital isolators.  This digital isolator is 10x more reliable than an optocoupler.
